Frequently asked questions
Where can you buy peptides in Canada?
From Canadian research vendors that ship domestically — avoiding the customs risk of importing. This directory lists vendors that state they publish batch lab testing and sell Research Use Only.
How are vendors chosen for this directory?
Listings are compiled from each vendor's own public website: Canadian/domestic shipping, published COA or lab-report documentation, and RUO framing. Details are the vendor's stated claims, which we report but do not independently audit.
Why avoid US peptide vendors when in Canada?
Cross-border shipments of substances that are prescription or unapproved drugs in Canada can be seized by CBSA. Domestic vendors remove the border from the transaction.
What should a peptide COA show?
Batch-specific results from an independent lab: purity by HPLC and identity by mass spectrometry at minimum. Stronger programs add endotoxin and sterility testing.
